Show HN: Pg_CRDT – an experimental CRDT extension for Postgres

  POC CRDT support in Postgres

  

This is an experimental extension for CRDTs, `pg_crdt`[0]. It supports Yjs/Yrs and Automerge.

The linked blog post describes how we're thinking about this extension in a Supabase context. Ideally this "Show HN" generates some discussion/interest, both here and in the github discussions [1].

I want to emphasise this part from the blog post[2]: "pg_crdt has not been released onto the Supabase platform (and it may never be). We’re considering many options for offline-sync/support and, while CRDTs will undoubtedly factor in, we’re not sure if this is the right approach."
